I'm sure most of you have seen it. The yin yang soap made in a Pringles can or PVC pipe. I've tried it a couple of times with moderate success. So yesterday I decided to try it again. The soap in the Pringles can all leaked out, so that was exciting. But I have always wondered if this could be done in a cavity mold. Turns out it can. I just cut some strips off a dollar store cutting mat. I just thought I'd share since it is something different to do with those little bits of batter that are left over.
